Problem running debugger for custom makefile project

Post by mass85 » Sat Oct 29, 2011 10:47 pm

I can not run debugger for Custom Makefile project, whenever I press F5 program exits immediately and there is no sign of my application's activity (nothing in logs etc.). I tried to insert a breakpoint without a result.

However if I run gdb from a command line, it works perfectly.

Here is the output in debug pane:

Try and change the debuggee process from:
"MainApp"

into

"./MainApp"

From: Project Settings -> General Page (under 'Program to Run/Debug)

It didn't help. I got the same result although this command (similar to the one used by CodeLite) run in shell works:
gdb --interpreter=mi "MainApp"

but this one does not work:
gdb --interpreter=mi "./MainApp"

because gdb can not find such file.

So it is strange that I don't get the same output in CodeLite. Moreover if I configure some rubbish commands (i.e. foo) to be passed to the debugger on startup and after attaching to process (in Project settings -> Common settings -> Debugger), I can't see these commands in the debug pane.

There is a little check box at the top of the debugger output tab ("Enable fill debugger logging"), please tick it - it will give us much more information

A quick questions:

can you post the snippet of code where you place your breakpoint?
Is it placed at the first line of code?

Code: Select all

int main(int argc, char *argv[]) {
     check_ver_arg(argc, argv);   // breakpoint
...
/* 
Initialisation of program. Start of threads
*/
}

Ok, here is your problem:
codelite places a breakpoint at the first line in the main function, however you set one too...
so when this breakpoint hits, codelite applies the user breakpoints and hit the 'Continue'.. so since you probably don't have other breakpoints - your programs runs until it exits.

To disable this functionality, go to the menu:
Settings | Debugger Settings | GNU gdb debugger | General

and disable the option
'Apply breakpoints after main function is hit'

It should fix your problem

Unfortunately it does not fix my problem. I had played with breakpoints and they never stopped the program. Moreover my program does not exit without logging anything. It all looks like program didn't even start.

I've googled "exit code 0177" and I found this:
Using host libthread_db library "/lib/libthread_db.so.1".
(gdb) b main
Breakpoint 1 at 0x8048a78: file helloworld.cpp, line 17.
(gdb) start
Breakpoint 2 at 0x8048a78: file helloworld.cpp, line 17.
Starting program: /home/tcmichals/examples/helloworld
/home/tcmichals/examples/helloworld: error while loading shared libraries: libb
ost_thread-gcc41-mt-d-1_35.so.1.35.0: cannot open shared object file: No such f
le or directory

Program exited with code 0177.
It is just an example but usually (or always) when 0177 is returned the problem was that some library was not found at start of application. Maybe in my case environment variables are not passed in the right way? How/where should I set them? Anyway it's strange that I don't get any error regarding file that was not found...

How did you start codelite?

Did you try starting it from the shell? (simply: codelite &)
It should inherit the shell environment
